IMPROVEMENT lN NUT AND BOLT FASTENINGS.

Specification forming part of Letters Patent No. 141,980, dated August 19, 1873 application led April 5, 1873.

To all whom c't may concern:

Be. it known that we, JOHN T. ANTILL, of Smiths Ferry, Beaver county, Pennsylvania, and WILLIAM J. SLOAN, of Liverpool township, in the .county of Columbiana and State of Ohio, have invented a new and useful Improvement in Lock Nut and Bolt; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing making part cured by its strap-ends being brought up against the sides of the nut and into the slot ofthe bolt and interlocked with each other;

To enable othersskilled in the art to make and use our invention, we will describe the construction and manner of use.

An ordinary threaded and headed bolt is represented at b, and c is the nut to be locked iu position. By any of the means usually employed for such purposes we yout a slot in the threaded end of the bolt, as at c, or make two or more such slots crossing each other. From sheet metal of suitable quality we cut blanks of the substantial form indicated in Fig. 2, and punch an eye, as at d. This eye is placed on the bolt under the nut, and after the nut is screwed home the endsc of the keeper part c are turned up against the opposite faces of the nut. One of the straps c' is placed in the slot c and interlocked with the other strap as at i.

It will readily be seen that the nut cannot turn unless the keeper turns, and that the keeper cannot turn while the straps (which mechanically constitute a bail) are interlocked with one of them in the slot c. It will also be observed that the bolt is as securely locked as the nut, and that neither can turn without the other.

We are aware that a wire has been passed through the body of a nut wound around the bolt, passed through the bolt, and the ends twisted together. This device requires the punching of an additional hole through the nut, which can be done only by a separate 0peration in a machine especially designed for the purpose, and after the nut is reheated.

What we claim as our invention, and desire` to secure by Letters Patent, is

The sheet-metal keeper c having an eye, d, and strap-ends e to bear against the sides ot the nut, arranged on the bolt under the nut, and secured by the bail 'i c' in the slot of the bolt, substantially as set forth.

In testimony whereof we, the said JOHN T. ANTILI. and WILLIAM J. SLOAN, have hereunto set our hands.

JOHN T. ANTILL. WILLIAM J. SLOAN.
